  1. Lightning is not a plasma. It makes plasma.
  2. @JustJoe. In case of lightening, it's a process.
  3. No, it is not. It is a phenomenon.
  4. @JustJoe. In the Modern and Theoretical Physics, where this thread is posted, electricity is not a substance.
  5. If each logical step of a derivation is written on a separate line, and preferably numbered, then it is easier to understand and discuss.
  6. Regarding the opening post examples: Null hypothesis: a deviation from an observed characteristic is a fluke, Alternative 1: a deviation is caused by population characteristic being greater than observed characteristic., etc.
  7. Not so. A god-like observer must rather conclude that particle falls into the event horizon in one reference frame and doesn't fall into it in another reference frame. No contradiction.
  8. An alternative hypothesis explains something as cause and effect, while a null hypothesis explains it as a statistical fluke.
  9. By definition, logical OR is inclusive, i.e., either one of the parts is true regardless of the other. An exclusive OR, which does not allow for both parts to be true together, is usually written as XOR.
  10. The developers of ChatGPT acknowledge these limitations of the system: (ChatGPT: Optimizing Language Models for Dialogue (openai.com))
  11. This article lists "best" uses for ChatGPT, and the last one is similar to what you did, I think. It also links to another article, about ChatGPT's limitations. The 5 Best Uses (So Far) for ChatGPT's AI Chatbot (cnet.com)
  12. I like that saying. Don't remember seeing it before and will use it often. Thank you, @swansont. Any known source?
  13. Correction: it is rather about 45 billion light years.
  14. The average distance a (general) particle travels, about 14 billion light years.
  15. One reason is that the moving parts of a device accelerate thus creating internal tensions.
  16. Yes, I have. The answers differed in wording, not in content.
  17. In my opinion, this "importance" function does not have a global maximum.
  18. We can conclude that this is a generic feature of science forums because this guy doesn't know anything about scienceforums.net specifically:
  19. I don't think it is normal or common to everybody. Perhaps it is not rare either, as a list of possible disorders with such symptoms come to mind. As an example, see Auditory Processing Disorder.
  20. Not all is bad in the ChatGPT world. Look at this:
